BRUSH .Foa Roan-MARKING MACHINES. v f

Application filed March 16, v1928. ySerial No. 262,144.

Broadly my invention has reference yto a machine for painting lines ofdemarcation on road'beds to indicate to traffic passing in oppositevdirections. that they arek to keep within the side of the road bed andthe warning line, and consequently prevent collision between suchvehicleswhich otherwise is very liable to occur.

Specifically the improvement is ldirected to a brush head or paintapplicator to be used in connection with a truck provided with a tankfor containing a marking fluid or paint and anothertank for forcing suchmarking fluid under pressure intothe brush or applicator, as forvinstance such road markingmachine as forms the subject matter of mycopending application Serial No. 164,036, filed by me January 27, 1927.

A further object is the provision ofv 4a 2O line in the center of aroadbed that is provided with a pointer guide for accurately directingthe same, guard brushes at the sides thereof, a painting or spreadingbrush at the rear or between the guard brushes, an

intermediate brush arranged atan inclination and directed toward therear brush, a

paint cup or receptacle that delivers the marking fluid onto thedirecting brush, .together with means forl pivotallyi supporting thebrush head on a support at one side lof the wheeled tank carrying truckand means for adjusting the brush angularly with respect to the roadbed. The invention will be fully and comprehensively understood from aconsideration of the followingy detailed description when vread inconnection with the accompanying drawings which form part of theapplication, with the understanding, however, that the improvement iscapable of'extended-ap-.

plication and is not confined to the exact Y Vshowing of the drawingsnor to the precise construction described, and, therefore, such;

-changes and modifications may be made therefrom as do not affect thespirit of the*` invention nor exceed the' scope thereof as expressed inthe appended claims.

In the drawings: Figure 1 is a top provement.

Figure 2 is a sectional view ap on the line 2-2 of Figure 1. v

Preferably thefbody of my' improvement is constructed of metal butobviously other suitable material can be employed. l .The brush head isindicated in the drawings by the numeral 1, thesame being of asubstantially rectangular formation, having at its upper face and itsouter edge a central longitudinally arranged notch or depression 2 and arectangular opening 3 in a line with 'lower edges of the shields beingcut atan inclination, and the top edges thereof being flanged andbolted,.riveted or otherwise securedto the under face of .the brush head1.

The rear brush is indicated by the numeral -6 and the bristles thereofare secured to the brush head, the said brush head, on the inner facethereof,fhaving secured thereto innerv and Aouterangle plates whosedepending flanges 7,v contact withl the inner and outer faces vat thetop portion of the spreading brush 6.

. Secured on the top of the plate constituting the brush head throughthe medium of rremovable Vmeans 8 thereare the solid ends v9 of a paintor marking Huid recelving cup 10. The cupis ofy a width greater than theVthe side walls formed by the depression 2. f

opening 3 #in the brush head and the outer face ofthe said cup,in a linewith the said openingis notched yor cut-away, as at 11, and the notchedor cut-away portion of the receptacleprovides theoutlet mouth thereof. YIntegrally formed on the ktop and Vat the centerof the receptacle 10there lis a tubular extension 12 having a threaded end portion 13 towhich is connected the hose leading from the fluid tank of thefmacliineto one side of which the vimprovement is attached.

Extending rearwardly from the flat and closed bot-tom of the receptacle10, and bolted theretmas at 14, there is a plate 15. This plate isarranged below and in the path of contact with a laterally extendingplate 16, and connecting the plates 15 and 16 there is adjustable means17. The means may comprise a bolt passing through the plates and engagedby a nut, as disclosed b the drawings or a wing nut that passes reelythrough the plate 16 and is threaded through the plate 15. Y

The plate 16 has an angleend which is bolted to one of the arms 18 ofthe support for the brush head or applicator. Both arms of the supportare provided with openings adjacent to their ends, and the walls ofthese openings afford bearings for short shafts or trunnions 19 thatextend from the closed ends 9 of the receptacle 10. The arms 18 havetheir rearportions connected by a shaft (not shown)` upon which thewheels for the truck (also not shown) are journaled.

One or both of the arms 18 of the support have attached thereto an eyemember 2O engaged by a rod which leads to the handle of the truck, andwhereby the brush may be raised orlowered and likewise whereby the4brush may be forced against the road bed with desired friction.

Seated in the depressed portion 2 of the plate or brush head 1 there isthe notched and straight end 21 of an angularly disposed plate 22 whichis received through the opening 3. Secured to the end of this plate22'there is a directing brush 23. This brush is normally disposed incontacting engagement with the paint spreading brush 6. The

plate 22 is secured on the brush head by removable means, suchA as abolt 24 which is engaged by a wing nut 25 and the bolt 24: passesthrough an opening, in the downwardly directed or i angularly disposedpointer guide 26. The pointerguide 26 is contacted by the wing nut 25-and thereby arranged forwardly and centrally with respect to the brushhead. It' desired, the plate 22 may be notched for the reception oftheinner end of the pointer guide therein.

As disclosed by Figure 2 of the drawings, a determined downwardlpressure upon the rear portion ot the brush headl will cause the brush 6of the applicator to spread away from the brush 23, consequently leavinga space between these brush elements for the passage of paint or other4marking fluid which will thus be directed onto the road surface forimprinting the line of demarcation thereon. Thus by adjusting thepressure applied to the brush head the quantity of paint delivered ontothe road" surface will be regulated'. The outer and lower ends ot theside and guard' brushes 4c are inclined and only when a determinedpressure is brought upon the. brush heads are these j edges of the guardbrushes brought against the road surfaces. The guard brushes prevent4the outward spreading of the mark made by the brushes 23 and 6. lVhenthe air is shut off from the air tank on the truck the device may betilted so that all of the paint remaining inthe pockets between thebrushes 23 and 6 and likewise the paint remaining inthe cup 10 may beredelivered into the paint tank and the brushes are normally returned toinitial position to close the paint outlet space therebetween. Thedevice may be read-ily cleaned as the directing brush is removablyattached to the brush head. Obviously the pr-esser rod need not beattached tov the link or eye but may have an angle end passing throughone of the arms 18 or may be attached to another part of theconstruction. A

v The simplicity of the construction and the advantages thereof will, itis thought, be apparent without further detailed description.

Having describedy the invention, I claim:
